In order to prepare porous PAN/PVdF nanofibers, PAN/PVdF/PMMA blend nanofibers were electrospun and then the PMMA was removed via a selective dissolution technique with chloroform. After extraction of the PMMA, the resulting PAN/PVdF nanofibers had highly porous surface. The surface morphology was characterized using scanning electron microscopy (SEM). The Brunauer-Emmett-Teller (BET) surface area of porous PAN/PVdF nanofibers made from PAN/PVdF/PMMA blend precursors is higher than that of PAN/PVdF nanofibers
